| 摘 要： | 以四川温江文化路干线为例,首先调查城市干线上各交叉口及路段的几何尺寸、交通流量流向、干线的容许车速,根据调查数据确定配时方案.取周期中最长者为公共周期.根据调查数据确定各交叉口相位差,用交通微观仿真软件VISSIM对实施交通协调控制的交通状况进行仿真.结果显示:经过交通协调控制后,干线上的大部分车辆能够以一定的行驶速度连续通过几个交叉口.

| Abstract: | Taking the trunk line of WenHua Road as example,this paper firstly investigates the geometrical measurement of the intersections and segments,and obtains the volume and direction of intersections and the restricted speeds of the segments.The signal timing scheme is made according to the investigated data and the longest cycle is taken as the share signal cycle.Based on the investigated data,the phase difference between each intersection is determined,and then the traffic situation where traffic coordinated ... |
